A manufacturing unit can produce one or more of the commodities A, B and C. If x units of A, y units of B and z units of C are produced then the cost of production is x + y + z (in Rupees) while the net profit equals f(x, y, z) (in Rupees). A total amount of Rs 30000 is available to cover the cost of production. If f(x, y, z) = x + 2y + 3z, then the maximum possible profit (in Rupees) is ??

Options are 60000,70000,80000,90000, 100000
